FIELD OF THE INVENTION

The present invention relates generally to a twin-bar pull handle, and more particularly to an innovative pull handle that is designed with two stop buttons of an activating mechanism for a controlled operation.

BACKGROUND OF THE INVENTION

The pull handles of luggage currently available are generally designed with a flexible structure, wherein the stop button is mounted at the top of pull handle for release of fixation, and then transferred to the fixation position of pull handlevia drive mechanism. In either single-bar or twin-bar configuration, the conventional luggage pull handle is designed with a single stop button at the top center of pull handle. Since manual holding of pull handle often generates the sense ofmishandling, the operators in this industry have developed a structure that two stop buttons are separately placed at both sides of the top of pull handle. However, such a twin-stop button structure is exclusively designed for the spatial configurationof single-bar pull handle. Thanks to robust construction, twin-bar pull handles are generally applied to medium or high-grade luggage with an extremely high market share. So, with intention to apply twin-stop button structure to this twin-bar pullhandle, there's no doubt that a braking and drive mechanism for the special configuration shall be developed for a smooth operation.

Thus, to overcome the aforementioned problems of the prior art, it would be an advancement in the art to provide a twin-button drive mechanism exclusively for the twin-bar pull handle.

BRIEF SUMMARY OF THE INVENTION

The present invention is directed to a twin-button braking mechanism exclusively designed for twin-bar pull handle. Thanks to the simple configuration and model design of a shared rotating drive element 50 along with two contact legs 41 42, itis possible to achieve an ease-of-manufacturing and installation for mass production with higher economic efficiency. During the driving process, a smooth and accurate drive can be made possible by pressing the contact legs in conjunction with theswinging action of shared rotating drive element.

The above is a detailed description of the technical features of the present invention based on a typical preferred embodiment. However, it should be appreciated that the present invention is capable of a variety of embodiments and variousmodifications by those skilled in the art, and all such variations or changes shall be embraced within the scope of the following claims.

DETAILED DESCRIPTION OF THE INVENTION

The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanyingdrawings.

As shown in FIGS. 1 4, there is a twin-bar pull handle with two stop buttons for luggage embodied in the present invention.

The invention includes a twin-bar pull handle A, which comprises two spaced riser pipes 11 12, a transverse holding rod 13 linked to the top of two riser pipes and a hollow horizontal tube 14 placed at lower space of transverse holding rod 13. Both sides of the hollow horizontal tube 14 are internally connected to the top of two riser pipes 11 12.

Two stop buttons 21 22 are separately mounted at both sides of transverse holding rod 13 of twin-bar pull handle. A pivot point 23 is provided at inner side of two stop buttons, and a spinner 24 at outer side for manual pressing.

Two brake rods 31 32 are separately placed into two riser pipes 11 12 of twin-bar pull handle, with its bottom connected to the preset fixation member no drawing available of pull handle. So, the pull handle can be operated flexibly by releasingthe fixation members via downward shift of two brake rods (this part is provided with the same fixation member as that of conventional luggage pull handle, so no detailed description is necessary).

The invention also includes two contact legs 41 42, with the top connected separately to the top of spinners 24 of two stop buttons 21 22, and the bottom protruding towards the top of two brake rods 31 32.

A shared rotating drive element 50 is transversely placed inside the hollow interior of hollow horizontal tube 14 of twin-bar pull handle, comprises a rotation axis 51 and two swinging sheets 52 53. The pull handle body is connected and limitedat both sides of rotation axis 51, making it possible to rotate around the fixed point of horizontal shaft. Two swinging sheets 52 53 are separately fixed at both sides of rotation axis 51, presenting a lateral stretching state. In this way, twoaforementioned contact legs 41 42 are separately stopped at top of two swinging sheets 52 53, while the top of two aforementioned brake rods 31 32 is separately stopped at the bottom of two swinging sheets 52 53.

Based on the above-specified structure and composition, the twin-button drive mechanism of twin-bar pull handle can function as detailed below.

As shown in FIGS. 3 4, when the user hasn't pressed the stop button, two swinging sheets 52 53 and two contact legs 41 42 of shared rotating drive element 50 can be supported by the upward reset characteristics of lower two brake rods 31 32, thuspresenting a rising spinner 24 of two stop buttons 21 22.

As shown in FIGS. 5 6, whenever the user presses either group of stop button 21 or 22, or press both of them simultaneously, the rotation axis 51 of a shared rotating drive element 50 can be enabled to rotate via the interconnected contact leg 41or 42. Moreover, the rotary swinging sheets 52 53 at both sides can be synchronized and pressed down, thus activating two brake rods 31 32 to shift downwards. As shown in FIGS. 8 9, the user can drive two brake rods 31 32 simultaneously by pressingstop button 22 or 21 via either left or right hand.

Of which, the top surface of two brake rods 31 32 can be designed with an expanded plate 33 fixed at the bottom of two swinging sheets 52 53.

Of which, two swinging sheets 52 53 and rotation axis 51 of the shared rotating drive element 50 can be integrally preformed, or provided with a fixed structure.

The contact legs 41 42 and stop buttons 21 22 can be integrally preformed, or provided with a fixed structure.
